Hi my friends,I'm now using 5610 as upconverter and 5600 as downconverter to IF Tranceiver 5641R.
If I directly wire CH0 AO to CH0 AI of 5641R,which means transmitting and receiving the signal at IF,the received signal in 5641R is showed in Pic 01.
If I directly wire RF Out of 5610 to RF In of 5600. Signal are tranceived at 2.4GHz from 5610 to 5600,and at 12.5MHz inside 5641R.In this case ,the received signal in 5641R is showed in Pic02.
As you can see,there is too much noise in Pic02,and the received signal is severely distorted.I wonder where the noise possibly could come from and how the distortion happened.
